Ching, My LX83 also has this problem. I suggest that u can use a remote app on iOS or Android to control & display the song info rather than using LX83's interface which is sluggish. Other than that, I don't have no problem with DLNA.
Can I stream music to my PS3 or Philips 9600 and all operation such as choosing songs at the IPad only? Because I don't want to switch on the TV and choose song.
Any Ching can help?
